    Cloud Foundry after Kubernetes: How a lighter community process, growing contributions, and a new path to Kubernetes are shaping the platform’s next chapter.


    In this episode of the Open Source Way podcast, Karsten speaks with Beyhan Veli about the current evolution of Cloud Foundry and the community behind it. They discuss how the project reorganized its contributor processes to make onboarding easier and more transparent, leading to a significant increase in community participation and RFC-driven innovation. Beyhan also shares updates on recent platform features, including cloud-native buildpacks, improved health checks, configurable routing algorithms, and IPv6 support. The conversation explores how Cloud Foundry and Kubernetes are increasingly seen as complementary technologies rather than competitors, culminating in a new initiative to enable Cloud Foundry deployments directly on Kubernetes. Together, they reflect on the renewed momentum in the ecosystem and what the future may hold for developers and contributors.
